Convert CSV, JSON, XML & Excel — offline, no row limit

CSVTools converts between CSV, JSON, XML and Excel — all directions — 100% offline. Nothing is uploaded. It streams row by row, so a 5-million-row file converts in flat memory with no row limit. Drag a file in, pick a format, click Convert; leave the output blank and it saves next to your input. Free Demo is a pure converter; Lite and Full add a visual editor to clean, filter, rename, dedupe and reshape — and save reusable jobs. No terminal required.

Hi PH 👋 I built CSVTools because every "quick" CSV↔JSON↔XML↔Excel conversion meant either pasting sensitive data into a website or wrestling a script. This does it 100% offline — drag a file in, pick a format, done — and streams, so there's no row limit (the GIF converts a 5M-row / 438 MB file).
Free Demo is a pure converter; Lite adds a visual editor to clean, filter and reshape, and Full adds merge / split / fan-out. No terminal needed.
